RF433 transceiver operates at a 433 MHz radio frequency, which falls under the Industrial, Scientific, and Medical (ISM) band. It commonly uses On-Off Keying (OOK) and Amplitude Shift Keying (ASK) as its modulation techniques for wireless data transmission. These methods are widely used due to their simplicity and reliability in short-range communication.
IR Transmitter is a module that emits infrared light, which is invisible to the human eye, to transmit signals wirelessly. It is commonly used in remote control systems and wireless data transmission between devices.
IR is an acronym for Infrared, a form of light energy that is invisible to the human eye. Infrared technology is widely used in remote control systems, such as those found in televisions, air conditioners, and other household appliances.
